Answer:
Saturday: 1.5x
Sunday: 2x
Explanation:
For the the Chart, Saturday, we can automatically see that when 1 is inputted into the equation we get 1.5, as anything times 1 will equal the same number inputted (x). So we can try 1.5x and plug in every other x value and see what we get:
1.5(2) = 3
1.5(3) = 4.5
1.5(4) = 6
This verifies that the equation 1.5x works with this chart.
For the graph its simple, do rise over run and your slope is 2/1 which is 2 so we have 2x for our equation so far and now to find the + or - at the end of the equation ( the "b" variable of the mx + b form) we just look at where does the function intersect with the Y-axis. Since it is at 0 we don't need to add a "b" variable to the equation so the equation for the graph is 2x for Sunday.
